PNEUMATIC CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 367,753, dated August2, 1887.

Application filed November 9. 1886. Serial No. 218,419. (No molleLi Toall whom, it may concern:

Be it known that I, JOHN L. GIVEN, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Pneumatic Cash Carriers, of which the following is afull, clear, and exact description.

This invention relates to improvements in pneumatic cash-carriers such,for instance, as are described and shown in Letters Patent of the UnitedStates, dated December 29, 1885, No. 333,379; and the invention consistsin the combination and arrangement of the valves, one to close and openthe opening in the trans mitting-standard of the pneumatic tube wherethe carrier, &c., are inserted for transmission through the tube, andthe other to open and close communication between the pneumatic tube andthe bellows or other air-motor in such manner that the closing oropening of one of Fig. 1. Fig. 4 is a central vertical section ofFig. 1. Fig. 5 is a partial front view of Fig.

3, portions being in central vertical section. Fig. (i is a view incross-section online 6 6, Fig. 1, looking up; and Fig. 7,a cross-sectionon line 7 7, Fig. 1, looking up. Fig. Sis a detail view, to behereinafter referred to.

In the drawings, A represents a transmitting-standard of a pneumatictube, B, for trans mission of a carrier, &c., therethrough, having ahead, G,which head is open at its lower end,

as at a, for the insertion and removal of a carrier, &c., and hascommunication with the chamber or passage D of the standard through anopening, I), the opening a having a valve, E, pivoted at c to thestandard.

The transmitting standard is secured by screws (1 to the top F of atable at the cashiers desk or central station,or at a salescounter orsingle station, having through an opening,f,

in the table-top F communication by its chamber I) with a bellows orother airmotor for v the passage of air through it, and to and throughmitting-standard has an intermediate pipe,

forming communication between it and the bellows, which pipe is providedwith a valve operated independently of the valve to the headopening,requiring two separate movements to operate the two valves; and theobject of this invention is to operate one of the valves by and from theoperation of the other,

preferably to operate the valve between the tube and bellows or otherair-motor by and from the operation of the valve to the headopening, sothat in closing the valve to the head-opening it will, through properconnections, open the valve between the tube and bellows, and thus thetwo valves will be operated by one operation, and this is accomplishedas will be now described.

G is a valve,hinged atg within the enlarged base of the standard, to beswung up to and close upon a seat, h, of the standard and close itspassage, to prevent air from the bellows passing through the standard tothe tube. The journal or pivot of this valve extends out through thecasing at one side, and has on its outer end a crank-arm, J, which haspivoted to it, at Z, one end of an upwardly-extending rod or arm, K,disposed in a guide-rest, m, of the standard. lhe journal or pivot c ofthe valve E also extends beyond the casing, haw ing at its outer end anarm, L, which, when the valve is open, projects upward, as shown in Fig.1, more particularly this arm being in the same vertical plane of therod K of the valve G.

After a carrier,&c.,are placed in the standard-head O for transmissionthrough its pneumatic tube, the valve E is closed, and as it swings upon its pivot its arm L moves correspondingly downward, and when thevalve E is nearly closed, as shown in dotted lines in Fig. 1, the arm IJstrikes or abuts against the upper end, 4'2, of-the rod K of thecrank-arm J of the valve G, and in its further closing movement pushessuch arm d0wn,and through its connection with the valve G by itscrankarm .I causes it to move away from its seat and open the passageDof the standard for air from the bellows, &c., to pass through the sameto act upon and transmit the carrier, &1c., through the tube. Thecarrier transmitted through the tube, the valve E is allowed to fall,which correspondingly raises its arm L, leaving the valve G free to beraised to close its opening 71., which is generally done by the pressureof air from the bellows, or it can be closed in any suitable manner whenthe tube is not to be used.

The lengths of the crank-arm L of the valve E and valve-arn1 J are soarranged in relation to each other and the necessary movements of thevalves that the valve E only acts upon the valve G during thelast partof its closing movement, for the reason that so soon as the valve G isopened, with the bellows in operation, air passes through the standard,and if the valveE is open, the air also passes out at its opening a,which is objectionable to the operator. There fore it is preferable toonly open the valveG in the manner described to prevent as much as ispossible air passing out at the opening a. The valves can be connectedtogether for operation by their arms, dispensing with the rod K, or bothvalves can be arranged on a common pivot, the seats for the valves beingcorrespondingly arranged to suit such connection; or the valves can beconnected and arranged to operate together in any suitable manner. Thevalve G can be operated by the valve E at any time during its movement;but it is preferable to have it moved as described, and, althoughpreferable to operate the valve G by the valve E, the operation can berevcrsed--viz., by operating the valve E from the valve G; also, thevalves can be arranged in the pneumatic tube itself, dispensing with astandard; but it is preferable to use the standard.

In lieu of holding the valve G closed by aii prcssure from the bellows,it can be held by other meansfor instance, by a spring, as shown indetail in Fig. 8, in which M is a spiral spring secured by one end tothe guidearm at and by its other end to the crank J of the valve G, thereaction of which spring when the valve G is free to move after beingopened will close the valve and so hold it when it is desired not to useits tube.

This arrangement and operation of the valves is particularly desired foruse at the cashiers desk or central station, where the pneumatic tubesfrom the several sales-counters or single stations meet, as the valvesin the intermediate pipes heretofore used can be dispensed with, as wellas the pipes themselves, as the transmitting-standards can be attachedto the bellows direct, if desired.

Having thus described my invention, what I claim, is

1. The combination, with a pneumatic tube for the transmission of'acarrier, &c., therethrough, of two valves, one arranged to open andclose communication between said tube and the operatingbellows or otherair-motor, and the other arranged to close and open the opening in saidtube through which the carrier, 850., is inserted and removed, thevalves being so connected together that as one or the other of said.valves is moved to open or close its respective opening the other valvewill correspondingly be closed or opened.

2. The combination, with a pneumatic tube for the transmission of acarrier, &c., therethrough, of a valve, G, arranged to open and closecommunication between said tube and the operatingbellows or otherair1notor, and a valve, E, arranged to close and open the opening insaid tube through whichthe carrier, &c., is inserted and removed, thevalve E being connected to the valve G in such manner that as it ismoved to close its opening in said tube it will cause the valve G toopen, for the purpose specified.

3. The combination, with a pneumatic tube for the transmission ofacarrier, 840., therethrough, of a valve, G,- provided with a crankarm,J, connected to an arm or red, K, and arranged to open and closecommunication between said tube and the operating-bellows or otherair-motor, and a valve, E, arranged to close and open the opening insaid tube through which the carrier is inserted and removed, andprovided with an arm, L, by which, as the valve E is moved to close, itsarm L will abut against said rod K and cause the valve to open,substantially as and for the purpose specified.

In testimony whereof have hereunto set my hand in the presence of twosubscribing witnesses.

JOHN L. GIVEN.
